Image control and HDR rendering

[Gavin-Williams]

I see that the image control supports jxr (jpg xr). Does the image control display a 16 bit rendertarget? Or does it get remapped to 8 bits. There is an open issue that WinUI doesn't support HDR #67 so I'm not sure if that issue affects the image control.

Also, do you see jxr as an alternative to exr and maybe even dds? I haven't gone over all the features, but jxr supports up to 32 bit color channels, an alpha channel, it has both lossy and lossless compression. It has tiled storage. So it seems to have broad utility, but not sure if it's quite as flexible as exr.

Update, looking at bmp, I didn't know I could use it for 16/32 bit images. How does that display in the image control ... correctly?
